GARDINER HALL, JR., OF WEST WILLINGTON, CONNECTICUT.

THREAD-DRESSING MACHINE.

Specification of Letters Patent No. 33,141, dated August 27, 1861.

To all 'whom it may concern:

Be it known that I, GARDINER HALL, J r., of 'West lillington, in the county of Tolland and State of Connecticut, have invented `a new and useful Improvement in Dressing right angles to each other, of such parts of a dressing machine as' are necessary to illustrate my improvement. Fig. 3 is a horizontal section of the same.

Similar letters of reference indicate corre sponding parts in the several figures.

To enable those skilled in the art to apply my invention to use I will proceed to describe it with reference tothe drawings.

is the framing of the dressing machine.

B is the rotating brush cylinder, having` its shaft C, in suitable bearings and having its periphery composed of a series of lags c, a, in which the brushes d, cl, are inserted, with openings b, between the lags.

E is a stationary semi-cylindrical box arranged under the lower half of the cylinder A, its length being just suicient to prevent the ends of the cylinderl from touching it in their revolution as shown in Fig. 2 and its width and depth being such that some room is left within it outside of the tips of the brushes, as shown in Figs. 1 and 3.

F is a stationary air trunk arranged on one side of the cylinder surrounding the shaft C, and having an opening c, c, around the shaft for the admission of air to the cylinder through one or more openings f, f, provided in the adjacent end thereof. This trunk connects with an `air-heating chamber in which air is heated by a furnace, by steam pipes, or by any other suitable means.

The brush cylinder, in its revolution, acts likev a blower drawing the dry heated air through its openings f, f, from the trunk F, and discharging it through the spaces b, b, between the brush lags c, c. The heated air which is discharged from the lower part of the cylinder into the box E, circulates through among and between the brushes and escapes at the sides of the said box to the atmosphere, and that which` is dis charged from the upper part of the cylinder escapes between the brushes direct-ly to the atmosphere, and such escaping air by reason of its heated and dry state greedily takes up the moisture from the sizing of the thread and carries it off while the brushes act upon the thread to dress it.

I do not claim the heating of air to dry the sizing in the dressing process by means of steam or hot air pipesor radiators arranged within the brush cylinder, but

What I claim as my invention, and desire to secure by Letters Patent, is

The combination ofthe following devices in the construction of brush cylinders of thread dressing machines,` to wit: the hollow cylinder, the brushes CZ, (l, upon its pe riphery, the openings I), b, between the rows of brushes, the end passages f, f, and the hot-air trunk F. communicating with the interior of the cylinder by means of the passages f, the several parts being constructed and arranged substantially as described.
